Abstract
In the present decade usage of Non linear loads and power electronic device in the industry sector has been increasing.Due to this the harmonics in the system get effected more and it get result in the Non linear electric loads. Harmonics are determined to have termendous effects on power system Equipment including Induction motor, Transformer, Conductors, Capacitor banks, Switchgear, and Protective relay. The count of harmonics producing loads has been have the drastic effect over the years. Now it has been became increasingly necessary to detect them by making changes to a system installation. Aiming towards the Improvement of Power Factor and Elimination of Harmonics induced in the system due to non-linear loads. This method helps to improve power factor and eliminate harmonics, so the power fed to the loads will be of better quality. This will not only reduce the penalization over consumers but also lead to run the load to their maximum efficiency. Further, the circuit of PF correction & detection similarly the Harmonics measurement and correction simulations are presented over Proteus Software. This tool helps to carry out trial and error method of the circuits. The calculated values will be fed to the Controller circuit which carry out programmed operations to get the desired outputs which are displayed over the LCD.
